Nevertheless, the present invention relates to a method for manufacturing a cover mounting body that can manufacture a cover mounting body having the same quality with a high yield.

  Conventionally, for example, long objects (also referred to as covered members) such as strings, rod-shaped bodies, chains, etc., are used for the purpose of preventing fraying or damage of long objects, connecting ends, and the like. In addition, various cover members such as connectors, locking pieces, protective members, and the like are often attached to the end portions and the like. As such a cover member, a cover member having elasticity (hereinafter sometimes simply referred to as a cover member) may be employed.

  As a method of attaching a cover member to the long object, for example, Patent Document 1 describes a cover fixing method and an apparatus for fixing a cover member to a cover member. Specifically, in claim 1, “a method of fixing an elastic cover member to a body to be covered, wherein the large diameter portion, the tapered portion, and the large diameter portion of the cover insertion member formed coaxially are arranged.

Method of fixing the cover, characterized in Rukoto "is described.

  Further, in claim 5, “a cover fixing device for fixing an elastic cover member to a body to be covered, wherein a small diameter portion, a taper portion, and a large diameter portion are formed coaxially, and the large diameter portion A cover insertion member having a hole for inserting the covered body, and pressing the elastic cover member while being inflated by elastic deformation, passing the small diameter portion, the taper portion and the large diameter portion, and the large diameter Cover pushing means for pushing into the covered body inserted into the hole of the part, and after the elastic cover member is pushed into the covered body, the cover inserting member is released and the elastic cover member is moved by elastic force. A cover fixing device characterized in that it is a device that is fixed integrally to the covered body is described.

  In other words, the “cover fixing method and apparatus” described in Patent Document 1 describes that “a small diameter portion, a tapered portion, and a large diameter portion are formed coaxially, and a hole for inserting a cover body into the large diameter portion is provided. A method of fixing the elastic cover member to the body to be covered by pressing the elastic cover member using “the cover insertion member provided” and “passing through the small diameter portion, the taper portion and the large diameter portion of the cover insertion member”; (See columns 0022 to 0027 and FIGS. 3 to 7 in Patent Document 1).

Japanese Patent No. 40156601

  However, the pushing member 5 and the pliers 9 and the pushing means 13 and 30 need to be manually operated as described in Patent Document 1. Then, since the cover member is usually long and has a small outer diameter, as described in Patent Document 1, “a part of the cover body is abutted in the hole of the large diameter portion. In the method of performing a plurality of subsequent steps while maintaining the “state”, the abutted state may change, and the elastic cover member may not be fixed to a predetermined position of the covered body. Furthermore, when a plurality of cover mounting bodies in which the elastic cover member is fixed to the body to be covered are manufactured by the cover fixing method and the cover fixing device of Patent Document 1, the cover state of the elastic cover member in the plurality of manufactured cover mounting bodies In some cases, the fixing position of the elastic cover member becomes non-uniform, and an elastic cover member having a predetermined quality cannot be manufactured with a high yield.

  On the other hand, in order to manufacture a plurality of elastic cover members by fixing the elastic cover member at a predetermined position of the cover body without changing the abutted state, extremely high skill is required.

  The cover mounting body manufactured by the cover mounting body manufacturing apparatus and manufacturing method according to the present invention is formed by mounting a cover member on a predetermined outer periphery or end of a long covered member. Examples of such a cover mounting body include ornaments such as a necklace, a bracelet, and a ring, and a long object such as a string, a rope, a chain, and a rod-shaped body. The cover member is a member attached to the covered member, and the shape thereof is not particularly limited as long as the cover member has a hole for attaching the covered member into which the covered member is inserted. An ellipsoid, a sphere, etc. are mentioned. Examples of such a cover member include a connector, a locking piece, a protective member, and the like. The cover member may or may not have elasticity, and the cover member may be attached to the cover member with its own elastic force or may be attached to the cover member with an adhesive or the like. In order to be attached to the covered member with elastic force, the cover member usually has an inner diameter smaller than the outer diameter of the covered member.

  In the cover mounting body manufacturing apparatus and manufacturing method according to the present invention, in general, a cover member can be mounted as desired even if it is a flexible cover member that is difficult to mount the cover member. Accordingly, the covered member serving as the base of the cover mounting body may be a long member that does not bend, such as a rod-like body, or may be a long member that can be bent. This covered member is adjusted to an appropriate outer diameter and axial length according to the application and the like.

  In the cover mounting body manufacturing apparatus and manufacturing method according to the present invention, as the cover mounting body, a decorative tool in which a connector is mounted on the long body for the decorative tool is preferable. Examples of such ornaments include a necklace (including a magnetic necklace in the present invention), a bracelet (including a magnetic bracelet in the present invention), a strap, a choker, and the like.

  The cover mounting body is, for example, a cover-covered member such that the cover-covered member 52 is inserted to substantially the center in the axial direction of the cover member 51, as in the cover mounting body 50 shown in FIG. The cover member 51 may be attached to the cover member 52. Further, like the cover attachment body 53 shown in FIG. 8B, in other words, the cover member 51 and the cover member 51 are covered over the entire axial direction of the cover member 51. The cover member 51 may be attached to the covered member 52 so that the covered member 52 is inserted into the cover member 51 until both end faces of the member 52 are substantially flush with each other. Specifically, when a connector having a connecting portion or the like in the vicinity of one end is used as the cover member 51, the connecting portion or the like (not shown in FIG. 8) is used as shown in FIG. For example, the cover member 52 is inserted into the cover member mounting hole 54 and mounted to the approximate center of the connector in the axial direction. As an example of such a cover mounting body, for example, as shown in FIG. 8A and FIG. 8B, the covered member 52 is mounted to substantially the center in the axial direction of the cover member 51 or over the entire axial direction.

The method for manufacturing a cover mounting body according to the present invention, which can manufacture the cover mounting body as described above, includes a control member having a control surface formed around a through hole that penetrates an outer tube having both ends opened. wherein the through hole is projected to the outer tube, the outer diameter change section of the center pole body gradually outer diameter toward the distal end has a smaller outer diameter change portion protruding from the distal end of the insertion and Teso in the outer tube in the step of inserting positioning said cover member, said cover member, and relative pusher to the outer pipe side along the axial direction of the center pole body, while expanded in the outer diameter change section the A step of covering and arranging the outer tube, a step of relatively retracting the tip of the middle shaft body at least into the outer tube, and a member to be covered in the outer tube in which the middle shaft body is retreated and becomes a cavity. a step of inserting arranged, the mosquitoes in the regulating surface And relatively retracting said outer tube with respect to the restricting member while restricting the retraction of the over member, and said cover member and a step of mounting the to the covered member.

  First, a cover mounting body manufacturing apparatus according to the present invention suitably used for carrying out a method for manufacturing a cover mounting body according to the present invention (hereinafter sometimes referred to as a manufacturing method according to the present invention), This will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, a cover mounting body manufacturing apparatus 1 according to an embodiment of a cover mounting body manufacturing apparatus according to the present invention (hereinafter sometimes referred to as a manufacturing apparatus according to the present invention) is shown in FIGS. 1 to 3. The insertion jig 10, the pushing member 20, the opening amount adjusting means 30 (see FIG. 2), and the insertion jig moving means 40 are provided.

  As clearly shown in FIG. 4, the insertion jig 10 in the manufacturing apparatus 1 includes a rod-shaped middle shaft body 11 and an outer tube 12 through which the middle shaft body 11 is inserted.

  As clearly shown in FIG. 4A, the middle shaft body 11 has a rod shape in which the large-diameter portion 14, the outer-diameter changing portion 15, and the small-diameter portion 16 share a central axis. Further, the cover member 52 has a tip restricting portion 18 that restricts displacement in the axial direction mainly. Specifically, the middle shaft body 11 is provided in a standing state on a first moving substrate 41A, which will be described later, and is provided continuously from a large diameter portion 14 having a substantially constant outer diameter and an end portion of the large diameter portion 14, An outer diameter changing portion 15 whose outer diameter gradually decreases toward the outer diameter, and a small diameter portion 16 which is provided continuously from the end of the outer diameter changing portion 15 and has a substantially constant outer diameter smaller than the large diameter portion 15. It is configured.

  The outer diameter of the large-diameter portion 14 only needs to be smaller than the inner diameter of the outer tube 12 to be described later. For example, as in the middle shaft body 11 shown in FIG. The outer diameter of the large-diameter portion 14 may be substantially equal to the inner diameter of the outer tube 12 so that the inner peripheral surface comes into contact with the inner peripheral surface. For example, like the middle shaft body 19 shown in FIG. The outer diameter of the large-diameter portion 14 ′ may be smaller than the inner diameter of the outer tube 12 so that the outer peripheral surface of the large-diameter portion 14 ′ and the inner peripheral surface of the outer tube 12 are not in contact with each other.

  The outer diameter changing portion 15 may be a frustum-shaped tapered portion whose outer diameter gradually decreases at a constant rate toward the tip, and has a curved surface whose outer diameter gradually decreases at a different rate toward the tip. It may be a curved surface portion, and in this example, the tapered portion.

  The small-diameter portion 16 has a tip restricting portion 18 at its tip, and its outer diameter may be substantially the same as or smaller than the inner diameter of the cover member 51.

  The axial lengths of the large-diameter portion 14, the outer-diameter changing portion 15, and the small-diameter portion 16 are appropriately adjusted according to the cover member 51, the covered member 52, and the like. The large diameter portion 14 arranges and supports the outer diameter changing portion 15 so that the outer diameter changing portion 15 protrudes from the distal end portion of the outer tube 12 when the middle shaft body 11 is inserted into an outer tube 12 described later. As long as it is a member and exhibits such a function, the form of the large diameter portion 14 is not particularly limited. For example, the large-diameter portion 14 may be a solid body, and the end portion may be open or closed.

  The middle shaft body 11 has the tip restricting portion 18 at the tip of the small diameter portion 16. In the present invention, the intermediate shaft body does not have to include the small diameter portion and the tip restricting portion. However, when the small shaft portion 16 and the tip restricting portion 18 are provided like the intermediate shaft body 11, the medium shaft body is inserted into the outer tube 12. Since the displacement can be regulated by abutting against the end face of the covered member 52, the relative positional relationship between the cover member 51 and the covered member 52 can be easily and stably maintained. This is particularly preferable in that a cover mounting body having the same quality can be manufactured with a higher yield. The tip restricting portion 18 may be in any form that can abut against the covered member 52 and restrict the displacement thereof, and is flat in this example.

  As shown in FIG. 4B, the outer tube 12 is a tubular member having both ends opened, and the middle shaft body 11 is inserted therethrough and in a direction opposite to the direction in which the middle shaft body 11 is inserted. In other words, the covered member 52 is inserted in the same direction as the direction in which the cover member 51 is pushed. The outer tube 12 has an inner diameter that is substantially the same as or larger than the outer diameter of the large-diameter portion 14 and the covered member 52, and supports and fixes the covered member 52 that is disposed to be covered. The outer tube 12 is shorter than the axial length of the middle shaft body 11, and in this example, when the outer tube 12 is provided in a standing state on a second moving substrate 41B, which will be described later, the distal end portion and the large diameter portion 14 of the outer tube 12. It has an axial length that is substantially coincident with the tip portion. The outer tube 12 is preferably adjusted to a thin thickness within a range in which the strength can be maintained in terms of easy insertion of the cover member 51.

  As shown in FIGS. 1 and 2, the insertion jig moving means 40 in the manufacturing apparatus 1 includes a first moving substrate 41 </ b> A on which the middle shaft body 11 is erected and a through hole 42 through which the middle shaft body 11 passes. And the second moving substrate 41B on which the outer tube 12 is erected so as to surround the through hole 42 while sharing the center with the through hole 42. The first moving substrate 41A and the second moving substrate 41B are respectively connected to driving means (not shown) such as a motor and a cylinder so as to be able to move forward and backward in the direction of the axis C of the central shaft body 11 independently.

  The pushing member 20 in the manufacturing apparatus 1 moves back and forth along the axis C direction of the middle shaft body 11, and covers the cover member 51 inserted and arranged in the middle shaft body 11 protruding from the outer tube 12 on the outer tube 12 side. The cover member 51 is a member that covers the outer tube 12 while expanding the diameter of the cover member 51 by the outer diameter changing portion 15. Specifically, as shown in FIGS. 1 to 3, the pushing member 20 is formed around a first through recess 24 </ b> A that forms a later-described through portion 27, and the first through recess 24 </ b> A. A first pushing arm 21A having a first pushing portion 22A having a first abutting portion 23A that abuts an end portion of the member 51, and a second pushing portion 27 together with the first penetrating recess 24A. A second pushing arm 21B having a second pushing portion 22B having a penetrating recess 24B and a second abutting portion 23B formed around the second penetrating recess 24B and abutting against the end of the cover member 51. Comprising.

  The first pushing arm 21A has a substantially quadrangular prism shape, and a first pushing portion 22A having a first penetrating recess 24A and a first abutting portion 23A at one end thereof. A first tip member 25A is mounted, and a first connecting member 26A (see FIGS. 1 and 2) connected to a pushing member moving means 44 described later is mounted on the other end.

  1 and 3, the first tip member 25A is a smooth plate-like member, and has a substantially semicircular shape penetrating in an end surface on the second pushing arm 21B side to be described later in the thickness direction. A first through-hole recess 24A is formed. That is, the first tip member 25A includes a flat surface and the first through recess 24A formed substantially perpendicular to the surface. The first pushing portion 22A includes the first through recess 24A and the first through recess 24A. It consists of a first abutting portion 23A that is a surface surrounding the penetrating recess 24A. As shown in FIG. 3, when the first pushing arm 21 </ b> A is supported by the pushing member moving means 44, the first tip member 25 </ b> A is desired to have the surface on the middle shaft body 11, and the end surface is the middle shaft. It is located so as to face the axis C of the body 11.

  The concave amount of the first through recess 24A is such that the concave surface of the first through recess 24A contacts the outer surface of the middle shaft body 11 when the pushing member 20 moves forward and the outer tube 12 is covered with the cover member 51. According to the outer diameter and inner diameter of the cover member 51, the shape and size of the first tip member 25A, and the amount of protrusion from the side surface of the first push arm 21A toward the second tip member 25B so as to be non-contact. Is determined as appropriate. In short, the amount of recess of the first through recess 24A is such that when the cover member 51 is pushed forward, the first contact portion 23A that contacts the cover member 51 exists, and the concave surface of the first through recess 24A is It is determined so as to be in contact or non-contact with the outer surface of the middle shaft body 11. As will be described later, it is preferable that the concave surface of the first through recess 24 </ b> A is not in contact with the outer surface of the middle shaft body 11.

  In the manufacturing apparatus 1, the first connecting member 26 </ b> A is pushed so that the first pushing arm 21 </ b> A is rotatably supported by the pushing member moving means 44 as shown in FIGS. 1 and 2, for example. A shaft body or the like that is supported by a bearing of the advance member moving means 44 is provided.

  The second pushing arm 21B is basically the same as the first pushing arm 21A, as shown in FIGS.

As shown in FIGS. 1 and 3, the first push arm 21 </ b> A and the second push arm 21 </ b> B include a through portion 27 formed by a first through recess 24 </ b> A and a second through recess 24 </ b> B that face each other. (Especially see FIG. 3), the first pushing arm 21A and the second pushing arm 21B are close to or remote from each other so that the center of the insertion jig 10 is located substantially on the axis C. The first penetrating recess 24A and the second penetrating recess 24B that face each other can be moved close to each other or remotely, in other words, each of the pushers can be rotated so that the penetrating portion 27 can be opened and closed. the first connection member 26A and the second connecting member 26B is supported by the member moving means 44.

  In the pushing member 20 thus supported, the through portion 27 is equal to or larger than the outer diameter of the small-diameter portion 16 in the middle shaft body 11 and is the same as the outer diameter of the cover member 51 inserted and arranged in the middle shaft body 11. Or it has the dimension used as less than the outer diameter. For example, in this example, as shown in FIG. 3, the penetrating portion 27 is a substantially circular cutout portion in which a substantially semicircular first penetrating recess 24A and a second penetrating recess 24B face each other. The diameter has a dimension in the above range. In this example, specifically, the diameter of the penetrating portion 27 is slightly larger than the outer diameter of the small diameter portion 16.

  As shown in FIGS. 1 and 2, the pushing member moving means 44 has a plate shape and serves as a bearing that supports the shafts of the first connecting member 26A and the second connecting member 26B therein. A recess is formed. The pushing member moving means 44 is connected to driving means (not shown) such as a motor and a cylinder so as to be able to move forward and backward together with the first pushing arm 21A and the second pushing arm 21B of the pushing member 20. Yes.

  The opening amount adjusting means 30 in the manufacturing apparatus 1 is configured so that the middle shaft body 11 moves according to the relative position of the pushing member 20 along the axis C direction of the middle shaft body 11, in other words, according to the forward and backward movement of the pushing member 20. It is a member that adjusts the separation distance, that is, the opening amount of the penetrating part 27 that penetrates. When the manufacturing apparatus 1 includes the opening amount adjusting means 30 that maintains the non-contact state between the penetrating portion 27 and the outer diameter changing portion 15 during operation, the insertion jig 10 and the penetrating portion 27 are damaged due to wear or the like. This is preferable in that the cover member 51 can be uniformly mounted on the covered member 52 and high durability can be exhibited.

The guide outer diameter changing portion 34 may be a frustum-shaped guide taper portion whose outer diameter gradually decreases at a constant rate toward the tip, and the outer diameter gradually decreases at a different rate toward the tip. A guide curved surface portion having a curved surface may be used, and in this example, the guide taper portion is used.

  The guide member 31 has outer diameters of the large diameter portion 35, the guide outer diameter changing portion 34, and the small diameter portion 36 so that the penetrating portion 27 has an opening amount that does not contact the outer peripheral surface of the outer diameter changing portion 15. The axial length is adjusted. In this example, the position (altitude) in the direction of the axis C between the penetrating portion 27 and a first guided portion 37A and a second guided portion 37B described later, and the inclination ratio of the outer diameter changing portion 15 in the intermediate shaft body 11 In consideration of the above, the inclination ratio and axial length of the guide outer diameter changing portion 34 and the axial length of the large diameter portion 35 are determined.

And a first guided portion 37A. As shown in FIG. 3, the first guided portion 37A is formed in a substantially arc shape penetrating in the thickness direction on the side surface of the flat rectangular column body on the first adjusting arm 35 side described later. It is a notch recess. The concave amount of the first guided portion 37A is determined so that the concave surface of the first guided portion 37A contacts the outer surface of the guide member 31 when the pushing member 20 moves forward and the outer tube 12 is inserted into the cover member 51. The shape and size of the flat rectangular column body, the amount of protrusion on the second guided portion 37B side from the first connecting portion 38A, the inclination ratio of the outer diameter changing portion 15 and the like are determined as appropriate. ing.

  The second adjustment arm 32B is basically the same as the first adjustment arm 32A, as shown in FIGS.

  As shown in FIGS. 2 and 3, the first guided portion 37 </ b> A and the second guided portion 37 </ b> B that face each other are positioned substantially on the axis of the guide member 31. The first guided portion 37A and the second guided portion 37B are slid on the outer peripheral surface of the guide outer diameter changing portion 34 in a state of being opposed to each other, so that the inclination ratio of the guide outer diameter changing portion 34 is increased. Accordingly, the distance between each other is remote or close.

For example, in this example, as shown in FIG. 3, the first guided portion 37A and the second guided portion 37B face each other to form a substantially circular space. The diameter of the space portion has a dimension in the above range. Specifically, in this example, the substantially circular space portion formed by the first guided portion 37A and the second guided portion 37B is The diameter is substantially the same as the outer diameter of the small diameter portion 36.

  As shown in FIG. 1, the elastic member 33 may be a member that can connect the first push arm 21 </ b> A and the second push arm 21 </ b> B close to or remotely from each other along the rotation direction. Examples thereof include a tension coil spring and a compression coil spring. In this example, a tension coil spring is installed as the expansion / contraction member 33 above the first pushing arm 21A and the second pushing arm 21B, that is, on the pushing member moving means 44 side. Accordingly, the pushing member 20 is normally brought into the initial state shown in FIGS. 1 to 3 by the telescopic member 33, and the first pushing arm against the stretching force of the telescopic member 33 by the opening amount adjusting means 30. 21A and the second pushing arm 21B are rotatable so as to be remote along the rotation direction.

  In this manufacturing apparatus 1, as shown in FIGS. 1 and 2, when the outer tube 12 is relatively retracted along the direction of the axis C, a cover is disposed on the outer periphery of the outer tube 12. A regulating member 46 that regulates or prevents the member 51 from moving backward in the same direction as the outer tube 12 is provided. The restricting member 46 is a flat plate having a through hole 47 through which the central shaft body 11 and the outer tube 12 pass, and a restricting surface that is formed around the through hole 47 and restricts or prevents the cover member 51 from retracting. It is a member. The restricting member 46 is connected to a driving means (not shown) such as a motor and a cylinder so as to be able to move forward and backward along the direction of the axis C independently of the first moving substrate 41A and the second moving substrate 41B. It arrange | positions in the position where the axial line length of the outer tube | pipe 12 which protrudes from the member 46 and the axial line length of the cover member 51 mentioned later become substantially the same.

  The drive timing and drive speed of the insertion jig moving means 40, the pushing member moving means 44, and the regulating member 46 in the manufacturing apparatus 1 may be controlled by a control device such as a computer, or manually controlled. Also good.

  Each member of the manufacturing apparatus 1 may be formed of a material having a certain level of strength, and examples of such a material include various resins and various metals. Each member can be produced by a known method such as molding, rolling, and grinding.

  Hereinafter, an example of the manufacturing method according to the present invention using the manufacturing apparatus 1 (hereinafter, sometimes referred to as one manufacturing method according to the present invention) will be described. 5 to 7, for the sake of convenience, the extension direction on the small diameter portion 16 side of the central shaft body 11 is referred to as the upper or front end direction, and the extension direction on the large diameter portion 14 side is referred to as the lower or rear end direction.

  In one manufacturing method according to the present invention, first, the manufacturing apparatus 1, for example, the insertion jig 10 and the pushing member 20 are arranged in an initial state. That is, as shown in FIG. 1 and FIG. 5A, the middle shaft body 11 is inserted into the outer tube 12 having both ends opened, and the outer diameter changing portion 15 of the middle shaft body 11 protrudes from the distal end portion of the outer tube 12. In this state, the first moving substrate 41A and the second moving substrate 41B are moved relatively back and forth along the direction of the axis C, and the insertion jig 10 is disposed. At this time, the restricting member 46 is relatively moved forward and backward along the direction of the axis C, and is disposed and fixed at a position corresponding to the axial length of the cover member 51 that covers the outer tube 12. In this example, the regulating member 46 is disposed at a position that is the same as the axial length of the cover member 51. The initial state of the insertion jig 10 thus arranged is not shown in the tip of the outer tube 12 and the large-diameter portion 14 (FIG. 5A), as shown in FIGS. 1 and 5A. The outer diameter changing portion 15 and the small diameter portion 16 protrude from the distal end of the outer tube 12.

  On the other hand, the pushing member 20 is arranged at a distance from the insertion jig 10 above the axis C direction. The initial state of the pushing member 20 is pushed so that the first pushing arm 21A and the second pushing arm 21B are substantially parallel to each other, as shown in FIGS. Suspended by the advancing member moving means 44, the center of the penetrating portion 27 is located substantially on the axis, and the center of the space formed by the first guided portion 37A and the second guided portion 37B is substantially the same as that of the guiding member 31. Located on the axis. In the initial state, the pushing member 20 is in contact with or slightly spaced from the end surface of the first tip member 25A and the end surface of the second tip member 25B, as well shown in FIGS. Oppositely, the opening amount of the penetrating portion 27 is minimized.

  In one manufacturing method according to the present invention, as shown in FIG. 5 (b), after the manufacturing apparatus 1 is placed in the initial state, the intermediate shaft body 11 that penetrates the outer tube 12 and protrudes from the distal end portion of the outer tube 12. The cover member 51 is inserted and disposed in In this example, the cover member 51 is inserted and disposed in part of the small diameter portion 16 and the outer diameter changing portion 15. At this time, since the small diameter portion 16 has an axial length longer than that of the cover member 51, as shown in FIG. 5B, the small diameter portion 16 penetrates the cover member mounting hole and Projects from the end face. And the cover member 51 is arrange | positioned in series with the outer tube | pipe 12 so that it may become substantially coaxial with a space | interval. The cover member 51 may be inserted and arranged manually or automatically by a cover member handling mechanism such as a robot arm.

  In the manufacturing method according to the present invention, the pushing member 20 is then moved forward relatively along the axis C direction downward. In this example, the first moving substrate 41A and the second moving substrate 41B are fixed and the pushing member 20 is advanced. Then, as shown in FIG. 5C, the first tip member 25 </ b> A and the second tip member 25 </ b> B of the pushing member 20 come into contact with the upper end surface of the cover member 51. At this time, the end surface of the cover member 51 abuts on the first abutting portion 23A of the first pushing portion 22A and the second abutting portion 23B of the second pushing portion 22B, and the small-diameter portion 16 contacts the penetrating portion 27. I have entered. Further, the small diameter portion 36 of the guide member 31 enters the space portion formed by the first guided portion 37A and the second guided portion 37B.

  In the manufacturing method according to the present invention, when the pushing member 20 is further advanced in the same direction, the cover member 51 is directed toward the outer tube 12 as shown in FIG. 6A. It is pushed while being inserted into the. As the cover member 51 is pushed toward the outer tube 12, the cover member 51 slides on the outer peripheral surface of the outer diameter changing portion 15, and the inner diameter thereof, that is, the cover member mounting hole 54 and the outer diameter are gradually expanded. The At this stage, as shown in FIG. 6A, since the first tip member 25A and the second tip member 25B have not reached the outer diameter changing portion 15, the first push of the push member 20 is performed. The arm 21 </ b> A and the second pushing arm 21 </ b> B maintain an initial state, that is, a substantially parallel state by the expansion / contraction member 33.

  As shown in FIG. 6B, when the pushing member 20 is further advanced in the same direction and the first tip member 25A and the second tip member 25B reach the outer diameter changing portion 15, immediately before or simultaneously. The opening amount adjusting means 30 causes the first pushing arm 21A and the second pushing arm 21B to move away from each other in the opposite directions with respect to the shaft body pivotally supported by the bearing of the pushing member moving means 44. To turn. That is, when the first guided portion 37A and the second guided portion 37B reach the guide outer diameter changing portion 34 of the guide member 31 and advance along the guide outer diameter changing portion 34, the first guided portion 37A and the second guided portion 37A The space portion formed by the guided outer diameter changing portion 34 is gradually expanded by the guided outer diameter changing portion 34, and the guided portion 37 </ b> B is separated. Then, the first adjustment arm 32A provided with the first guided portion 37A and the second adjustment arm 32B provided with the second guided portion 37B are similarly separated from each other, and the first pressing arm combined with the first adjustment arm 32A is provided. Similarly, the advance arm 21A and the second push arm 21B to which the second adjustment arm 32B is coupled are separated from each other. Then, as the pushing member 20 advances downward, the space portion is gradually and greatly expanded by the inclination ratio of the guide outer diameter changing portion 34. As a result, the penetrating portion 27 is not in contact with the outer surface of the middle shaft body 11 in accordance with the relative position of the pushing member 20 along the axis C direction, and the inclination ratio of the outer diameter changing portion 15 of the middle shaft body 11 The diameter is expanded according to

  In this way, the first pushing arm 21A and the second pushing arm 21B are separated from each other, and as shown in FIG. 6B, the pushing member 20 includes the penetrating portion 27, the outer diameter changing portion 15, and the like. The cover member 51 is pushed to the outer tube 12 side while maintaining the non-contact state.

  When the pushing member 20 is further advanced in the same direction, as shown in FIG. 6C, the first pushing arm 21A and the first pushing arm 21A according to the relative position of the pushing member 20 along the axis C direction. While being separated from the second pushing arm 21 </ b> B, the cover member 51 is pushed up until the end of the cover member 51 comes into contact with the regulating member 46, and the cover member 51 is mounted on the outer peripheral surface of the outer tube 12, that is, is covered. At this time, since the cover member 51 completely covers the outer peripheral surface of the outer tube 12 and is expanded in diameter, the outer tube 12 is pressed by the elastic force in the central axis direction of the substantially uniform axis C in the circumferential direction. In this state, it is in close contact with the outer tube 12. Thereafter, as shown in FIG. 7A, the pushing member 20 moves backward in the direction of the axis C, enters an initial state, and stands by.

  In the manufacturing method according to the present invention, as shown in FIG. 7A, the intermediate shaft body 11 is then moved downward in the direction of the axis C, in other words, the relative exterior of the cover member 51 to the outer tube 12. It is made to retreat relatively at least into the outer tube 12 in the direction. In this example, the tip regulating portion 18 of the middle shaft body 11 is relatively retracted at least into the outer tube 12 to form a cavity in the distal direction of the outer tube 12. Specifically, the second moving substrate 41B is fixed, and the first moving substrate 41A is retracted downward. At this time, the retraction amount of the tip restricting portion 18 is appropriately adjusted according to the mounting state of the cover member. For example, when manufacturing the cover mounting body 50 shown in FIG. As shown in FIG. 7 (a), the tip restricting portion 18 is retracted to substantially the center of the axis of the outer tube 12, while the cover mounting body 53 shown in FIG. 8 (b) is manufactured. The middle shaft body 11, preferably the tip regulating portion 18, is retracted until it is substantially flush with the lower end of the outer tube 12.

  In the manufacturing method according to the present invention, as shown in FIG. 7 (b), the covered member 52 is then placed inside the outer tube 12 in which the middle shaft body 11 or the tip restricting portion 18 is retreated and becomes a cavity. The cover member 51 is inserted from the starting direction side in the pushing direction, that is, from the upper side, and inserted into the outer tube 12. In this example, as shown in FIG. 7B, the covered member 52 is inserted from the pushing direction starting point side until the end surface of the covered member 52 comes into contact with the tip restricting portion 18. The inner tube 12 is inserted and arranged. At this time, the insertion amount of the covered member 52 into the outer tube 12 is basically the same as the retraction amount of the middle shaft body 11 or the tip restricting portion 18 in the outer tube 12. In this way, when the covered member 52 is inserted and arranged in the outer tube 12, the displacement of the covered member 52 in the direction of the axis C is restricted by the tip restricting portion 18, and in the direction other than the direction of the axis C. The displacement is regulated by the outer tube 12 and is held so as to be in a desired insertion state. When the end surface of the covered member 52 is not brought into contact with the tip restricting portion 18, the displacement of the covered member 52 can be restricted by holding the covered member 52 with a holder such as a clamp. The covered arrangement of the covered member 52 may be performed manually or automatically by a covered member handling mechanism such as a robot arm.

  In the manufacturing method according to the present invention, as shown in FIG. 7C, the second moving substrate 41B on which the outer tube 12 is erected is moved backward relatively. In this example, the regulating member 46 is fixed and the second moving substrate 41B is moved backward. Then, the outer tube 12 moves backward in the same direction against the adhesion force of the cover member 51. At this time, since the end portion of the cover member 51 disposed on the outer tube 12 is in contact with the regulating member 46, the cover member 51 cannot be retracted together with the outer tube 12 and is attached to the outer tube 12. Stay in the position. That is, the cover member 51 does not retreat relatively upward in the direction opposite to the direction inserted in the outer tube 12 and does not pass through the middle shaft body 11 and the outer tube 12.

  When the second moving substrate 41B is moved backward in this manner, as shown in FIG. 7C, the cover member 51 having an inner diameter smaller than the outer diameter of the covered member 52 is a portion where the outer tube 12 is retracted. Therefore, the elastic force is applied to the covered member 52 arranged inside the cover member 51 in the direction of the center axis of the axis C which is substantially uniform in the circumferential direction. Close contact with. Subsequently, when the second moving substrate 41B is moved backward in the same direction, the cover member 51 is mounted in close contact with the covered member 52 as shown in FIG.

  Thus, in one manufacturing method according to the present invention, when the cover member 51 is attached to the covered member 52, the cover member 51 does not pass through the outer tube 12, in other words, the upper surface of the outer tube 12 is folded. It moves and is attached to the covered member 52. The cover mounting body manufactured in this way is taken out from the manufacturing apparatus 1. The step of removing the cover mounting body may be performed manually or automatically by a cover mounting body extraction mechanism such as a robot arm.

  In the manufacturing method according to the present invention, as shown in FIG. 5A, the insertion jig moving means 40 and the regulating member 46 are then returned to the initial state.

  In the manufacturing method according to the present invention, a desired cover mounting body in which the cover member 51 is mounted on the covered member 52 can be manufactured in this manner. In order to manufacture a plurality of cover mounting bodies, a series of steps shown in FIGS. 5A to 7D are repeatedly performed.

  In one manufacturing method according to the present invention, a step of inserting and arranging the cover member 51 in the middle shaft body 11 projecting from the outer tube 12, a step of covering and arranging the cover member 51 on the outer tube 12, and retreating the middle shaft body 11 And a step of inserting and arranging the covered member 52 in the outer tube 12 and a step of retracting the outer tube 12. In this manufacturing method, the displacement of the covered member 52 is regulated by the outer tube 12, and preferably, the displacement of the covered member 52 in the axial direction is regulated by the tip regulating portion 18. One of the features is that the step of inserting and arranging in the outer tube 12 is performed after the step of covering and arranging the cover member 51 on the outer tube 12. Furthermore, in this one manufacturing method, one feature is that the cover member 51 is attached to the covered member 52 without passing through the outer tube 12. In particular, the use of the insertion jig 10 composed of the central shaft body 11 and the outer tube 12 makes it possible to easily and accurately implement the above features. And since one manufacturing method which concerns on this invention has the said characteristic, although each process is simple, it is the cover member 51 and the to-be-covered member 52 which are arrange | positioned through the outer tube | pipe 12. The relative positional relationship can be easily and stably maintained until the manufacture of the cover mounting body is completed.

  In particular, in the manufacturing method according to the present invention, the step of covering and mounting the cover member 51 on the outer tube 12 is performed by the forward operation of the pushing member 20, and the step of retracting the outer tube 12 is performed by the second moving substrate 41B. Since it can be implemented by a reverse operation, the cover member 51 can be attached to the covered member 52 as desired without requiring operator skill. In particular, when the forward operation of the pushing member 20 and the backward operation of the second moving substrate 41B are semi-automated or automated by adopting drive means and control means, the cover member 51 is mounted on the covered member 52 with higher accuracy. be able to. Therefore, even if a large number of cover mounting bodies are manufactured by one manufacturing method according to the present invention, the majority of the cover mounting bodies have substantially the same insertion length of the cover member 51, mounting state of the cover member 51, etc. The cover member 51 has the same quality that is uniformly attached to the covered member 52.

  Therefore, although the manufacturing method according to the present invention is a simple manufacturing method, it is possible to manufacture a cover mounting body having an equivalent quality with a high yield.

  Further, in the manufacturing method according to the present invention, it is not necessary to pass the cover member 51 in the axial direction of the insertion jig 10, and the cover member 51 can be attached to the covered member 52 only by retracting the outer tube 12. Therefore, the time required for manufacturing the cover mounting body can be shortened.

On the other hand, the manufacturing apparatus 1 includes the insertion jig 10, the pushing member 20, the insertion jig moving means 40, and the regulating member 46 constituted by the middle shaft body 11 and the outer tube 12. It is suitably used for carrying out such a manufacturing method, and the relative positional relationship between the cover member 51 and the covered member 52 arranged via the outer tube 12 can be easily stabilized until the manufacture of the cover mounting body is completed. Can be retained. Therefore, according to this manufacturing apparatus 1, the cover mounting body which has equivalent quality can be manufactured simply and with a sufficient yield.

  Since the manufacturing apparatus 1 includes the opening adjustment means 30 and the penetrating portion 27 is not in contact with the outer diameter changing portion 15 during operation, the insertion jig 10 and the penetrating portion 27 may be damaged due to wear or the like. In addition, the cover member 51 can be uniformly attached to the covered member 52 over a long period of time, and high durability is exhibited.

  Further, the manufacturing apparatus 1 is configured to retract the outer tube 12 without passing the cover member 51 in the axial direction of the insertion jig 10 when the cover member 51 is attached to the covered member 52. Therefore, the time required for manufacturing the cover mounting body can be greatly reduced.

  The apparatus for manufacturing a cover mounting body according to the present invention is not limited to the above-described embodiments, and various modifications can be made within a range in which the object of the present invention can be achieved.

  In the manufacturing apparatus 1, the insertion jig 10 includes the middle shaft body 11 and the outer tube 12. In this invention, the insertion jig includes a third jig in addition to the middle shaft body and the outer tube. It may be. For example, a tubular member that surrounds the outer tube and is coaxially disposed outside the outer tube and that guides the pushing of the cover member to the outer tube from the outside may be provided. The tubular member has an inner diameter adjusted to be equal to or greater than the outer diameter of the cover member.

  In the manufacturing apparatus 1, the middle shaft body 11 includes the small diameter portion 16 and the tip restricting portion 18. In the present invention, the middle shaft body may not include at least one of the small diameter portion and the tip restricting portion. The tip surface of the tapered portion may be used as the tip restricting portion.

  In the manufacturing apparatus 1, the first pushing arm 21 </ b> A and the second pushing arm 21 </ b> B are directly connected by the telescopic member 33. In the present invention, the first pushing arm and the second pushing arm are: If these are connected in proximity or remotely, they may not be directly connected by the expansion / contraction member. For example, the first adjustment arm and the second adjustment arm are directly connected by the expansion / contraction member, so that the first The push arm and the second push arm may be indirectly connected.

  In the manufacturing apparatus 1, the first through recess 24A and the second through recess 24B have the same amount of recess in the thickness direction of the first tip member 25A and the second tip member 25B. The first penetrating recess and the second penetrating recess may be semi-conical recesses whose recesses become smaller toward the pushing member moving means. Similarly, the first guided portion and the second guided portion may be semi-conical concave portions whose concave amount is reduced toward the pushing member moving means. In addition, the decreasing rate of the recessed amount in these semi-conical concave portions may be the same as or different from the inclination rate in the outer diameter changing portion or the guide outer diameter changing portion.

  In the manufacturing apparatus 1, the first moving substrate 41 </ b> A on which the middle shaft body 11 is erected and the second moving substrate 41 </ b> B on which the outer tube 12 is erected are connected to driving means (not shown). Each of the first moving substrate and the second moving substrate may include a grip portion so that the first moving substrate and the second moving substrate can be moved forward and backward independently, for example.

  Although the manufacturing apparatus 1 has one each of the insertion jig 10, the pushing member 20, and the opening amount adjusting means 30, in the present invention, the insertion jig, the pushing member, and the opening Each of the amount adjusting means may include a plurality of groups arranged in, for example, an arrangement pattern along one direction or a two-dimensional arrangement pattern such as a grid pattern. For example, FIGS. 5 to 7 are diagrams for explaining a method for manufacturing a cover mounting body according to the present invention. FIGS. 5 and 6 illustrate the insertion jig, the pushing member, and the opening amount adjusting means 3. It can also be considered that the manufacturing apparatus is arranged in a row and each process is performed with a time difference. FIG. 7 shows the insertion jig, the pushing member, and the opening amount adjusting means 4 groups. Can be regarded as a manufacturing apparatus arranged in a row and performing each process with a time difference.

  As shown in FIGS. 2 and 3, the manufacturing apparatus 1 includes a pushing member 30 having the first pushing arm 21 </ b> A and the second pushing arm 21 </ b> B. The member only needs to be a mode in which the cover member can be pushed relatively to the outer tube side. For example, a plate-like member having a through hole, specifically, “push-in” shown in FIG. “Member 5”, “Plier 6” shown in FIG. 9 of Patent Document 1, “Holding member 26” shown in FIG. 30 of Patent Document 1, and the like can be used. In the manufacturing apparatus 1, the first pushing arm 21A and the second pushing arm 21B are rotatably supported by the pushing member moving means 44. In the present invention, For example, at least one of the second pushing arms may be supported by the pushing member moving unit so that the penetrating recesses are close to or remote from each other.

  In the manufacturing apparatus 1, the intermediate shaft body 11 and the guide member 31 are manufactured and fixed so that the positions (altitudes) of the outer diameter changing portion 15 and the guide outer diameter changing portion 34 in the axis C direction are different. However, in this invention, the intermediate shaft body and the guide member may be manufactured and fixed so that the positions (altitudes) of the outer diameter changing portion and the guide outer diameter changing portion are the same. In this case, the outer diameter changing portion of the intermediate shaft body and the guide outer diameter changing portion of the guide member have the same inclination ratio and axial length, and further, the penetrating portion, the first guided portion, and the second guided portion. In the guide portion, in particular, the end surfaces on the side of the middle shaft body have the same position (altitude) in the axial direction of the middle shaft body.

  The manufacturing apparatus 1 includes a guide member 31 having a large-diameter portion 35, a guide outer diameter changing portion 34, and a small-diameter portion 36. In the present invention, the guide member may not have a small-diameter portion. In addition, the large diameter portion may have an outer diameter smaller than the outer diameter of the guide outer diameter changing portion as long as it can support the guide outer diameter changing portion.

  In the manufacturing apparatus 1, the large-diameter portion 35, the guide outer-diameter changing portion 34, and the small-diameter portion 36 of the guide member 31 are arranged so that the through-hole 27 has an opening amount that makes no contact with the outer peripheral surface of the outer diameter changing portion 15. Although the outer diameter, the axial length, etc. are adjusted, in this invention, the guide member has a large-diameter portion and a guide outer portion so that the opening is open so that the penetrating portion contacts the outer peripheral surface of the outer-diameter changing portion. The outer diameter, the axial length, etc. of the diameter changing portion and the small diameter portion may be adjusted.

  In the manufacturing apparatus 1, the regulating member 46 can be disposed at a position where the axial length of the outer tube 12 protruding from the regulating member 46 and the axial length of the cover member 51 are substantially the same. The regulating member only needs to be arranged at an appropriate position according to the insertion length of the cover member into the covered member.
